Audient iD4 MKII 2-In/2-Out USB-C Audio Interface

The Audient iD4 MKII is a compact 2-in/2-out USB-C audio interface that brings a fully discrete Audient Console mic preamp—the same all-discrete, high-grade op-amp circuit design found in the ASP8024-HE recording console—into a 5.1 × 4.7 inch footprint. One channel of 58dB gain with ultra-low noise and classic analogue warmth pairs with 32-bit AD/DA converters and 126dB of dynamic range, and a JFET instrument input replicates the input stage of a classic valve amplifier for guitar and bass direct recording. Dual headphone outputs (1/4 in. and 1/8 in.), a Monitor Mix feature for zero-latency input blending, and audio loopback for streaming round out a feature set that exceeds what the form factor suggests. Bus-powered via USB-C (USB 3.0 required) with true +48V phantom power and iOS compatibility, the iD4 MKII travels as well as it performs on the desk.

Key Features

• Audient Console mic preamp — fully discrete, all-discrete high-grade op-amp design from the ASP8024-HE recording console; 58dB gain range; ultra-low noise and distortion with classic analogue warmth
• 126dB dynamic range converters (32-bit) — advanced 32-bit AD/DA technology for clean, precise conversion; wide dynamic range for accurate capture and monitoring
• JFET instrument input — harmonically rich circuit replicates the input stage of a classic valve amplifier; ideal for guitar and bass direct recording
• Dual headphone outputs — engineer-grade headphone amp capable of driving headphones up to 600 Ohms; 1/4 in. and 1/8 in. connections for two simultaneous listeners
• Stereo line outputs — connect a pair of studio monitors for accurate playback and mix referencing
• Monitor Mix — blend mic/instrument input directly with backing track at zero latency; record while monitoring both sources without software processing delay
• Audio loopback — capture mic input and computer audio simultaneously; dedicated loopback mixer for content creation, podcasting, and streaming
• USB bus powered — no external power supply required; true +48V phantom power per channel available bus powered; USB 3.0 connection required
• iOS compatible — records high-resolution audio directly to iPhone or iPad
• All-metal construction — compact 5.1 × 4.7 in. footprint; lightweight and portable; built for desktop and travel use
